Violin Sizes Explained: All You Need to Know!

Latest posts by Miah Schmahl (see all)

Small children are unable to hold or play a full-size violin. Depending on the age of a student, they may not be able to lift a full-size violin. That’s why we have fractional violins or violins that are smaller. These allow young students, some as young as three years old, to play the violin. As the student grows, the violin will grow with them. Meaning you, the parent, will have to trade in or trade up your child’s violin as they grow. Don’t worry; most places offer trade-in credit for owned violins, and you can generally trade rental violins for free.

Violin Sizes and Measurements

There are nine violin sizes sold as standard. Despite, this many luthiers debate the actual size of a violin, and older violins can be found in various sizes and still be a full-sized violin. These measurements are taken by measure the body of the violin and do not include the neck, pegbox, or scroll.

  • 1/32 = 7.5″
  • 1/16 = 8″
  • 1/10 = 9″
  • 1/8 = 10″
  • 1/4 = 11″
  • 1/2 = 12.5″
  • 3/4 = 13″
  • 7/8 = 13.5″
  • 4/4 = 14″

How to Measure Your Child/Student

There are a few quick but inaccurate ways to measure your child against the size of an instrument.

  • First, have them hold the violin under their chin as if they were going to play the instrument.
  • Second, have them stretch their hand and wrap it around the scroll of the violin. The violin is a good size if they can do this comfortably and without overstretching their arm.

Luthiers and music stores will also have devices that can help measure your child easily. You can also do it the old-fashioned way and measure your child/student from their shoulder to the tip of their fingers and compare it to these measurements below.

  • 13.5 to 14 inches is equal to 1/32 sized violin.
  • 14 inches is equal to a 1/16th sized violin
  • 15 inches is equal to a 1/10th sized violin.
  • 16.5 inches is equal to a 1/8th sized violin.
  • 18-18.5 inches is equal to a 1/4th sizes violin.
  • 20 inches is equal to a 1/2 sized violin.
  • 21.5 to 22 inches is equal to a 3/4 sized violin.
  • 22 to 23 inches is equal to a 7/8th violin. A 7/8th violin is meant for a smaller adult.
  • 23 inches is equal to a 4/4 or full-sized violin.

Typically by the time students are 11 or 12 years old, they are playing a full-sized instrument. If your child starts playing in elementary school, you can expect them to grow a size every year until they reach a 3/4th sized instrument around the age of nine.

Buying vs. Renting a Fractional Sized Violin

The decision to buy versus rent a fractional-sized violin for your growing student will depend on a few factors, including a budget, convenience, and your child’s size when starting.

If you are sentimental, you may want to purchase a fractional-sized violin for your student to keep as a souvenir as they grow. Many violinists still have their first violin and save it as a decoration. Fractional-sized violins are usually cheaper than their full-sized counterparts but can be hard to find compared to a 3/4 or 4/4 sized violin. Your local music store or luthier will be able to track down fractional instruments in your budget. I only recommend purchasing fractional instruments if you have multiple children using different sizes, are willing to sell or trade-in the violin for less than you paid, and can foot any repair or replacement costs if something happens to the instrument.

Depending on location, renting a violin will cost a fixed amount of money per month, usually under 50 dollars a month. I can currently get a fractional-sized violin rental for 20 dollars where I live in the midwest. Over time a percentage of what you pay each month will go towards purchasing a violin. Most rental places allow you to trade in violins for a larger size for free. Overall, renting a violin is highly convenient because you don’t have to spend time selling or trading your instrument. It can feel a little confusing, depending on the terms of the contract. I recommend deals that apply at least 50% of your payments towards owning a violin.

Additionally, rentals typically come with a form of insurance that will allow for any damages or repairs to be made for free. Violin repairs can be expensive, even on cheaper instruments. Knowing you can take it to the store if something goes wrong is a significant piece of mind.

If your child is already around nine years old when they express interest in the violin, then buying them a 3/4 sized instrument isn’t a bad idea. Typically students stay with a 3/4 sized violin for 2-3 years versus one year for smaller sizes. Some small adults may continue using a 3/4 sized violin or may need a 7/8th violin. Additionally, due to the demand for 3/4 sized and 4/4 sized violins, you can find buyers or better trade-in deals as well.
